In WoT Blitz, a new feature called “tank anniversary” appeared. Each tank in your garage has its “birthday” on the date of purchase. Every 3 months (precisely, every 91 days) the tank has an “anniversary”.

There are the following bonuses connected to this:
– x5 to first victory of the day
– x2 credit income
– bonus is available for one-time use only and expires after 3 days
– bonus also applies to premium vehicles

“This is a known issue and a fix is currently being developed. There is an update error with the account management profile as it attempts to synchronize with the game client to display the amount of Gold and credits in the account, but is displaying incorrectly. Anything shown on the website is not a clear representation of what’s actually on your account. The error is reproducible when you log in and out of account management, which will give you different Gold and premium amounts each and every time. ”
